Чести проблеми и решения

Stringing

Information about the TruPrint 3000 is not present in the sources, so general FDM best practices are applied; you may want to independently verify specific Trumpf data. Thin strands resembling a spiderweb appear between separate parts of the printed object [1]. Решение: Dry the filament for 4-6 hours at 50 °C for PLA or 70 °C for Nylon [2]. Increase the retraction distance by 1-2 mm, reduce the nozzle temperature by 5 °C, and increase the travel speed to 200 mm/s [2].

Warping

Corners or edges of the print detach from the platform and curl upwards due to uneven cooling and thermal stress [2]. Решение: Increase the bed temperature by 5 °C, add a 5-10 mm Brim, and use an enclosure if printing with ABS or Nylon [3]. Additionally, apply an adhesive like a glue stick and reduce part cooling to 30 % for the first 5 layers [3].

Under-extrusion

Thin, brittle walls and structural gaps appear on the surface of the part due to partially clogged nozzles or incorrect extruder steps [4, 5]. Решение: Perform a ‘Cold pull’ procedure, calibrate the E-steps using the M92 command, and increase the nozzle temperature by 5 °C [5].

Подходящи приложения

• Automotive Jigs & Fixtures: Manufacturing specialized production templates that are subjected to heavy mechanical loads, requiring a tensile strength of over 100 MPa [6].
• Rapid Prototyping: Verifying form, performing fit-checks, and testing ergonomics in a matter of hours rather than days [7, 8].
• Certified Aviation Components: Printing critical functional components for aircraft interiors that require extreme strength and temperature resistance, typically using industrial materials like PEI (ULTEM) [9, 10].
